    Ensure that mixture is delivered to the paver at highest allowable temperatures. As mix delivery temperature is typically under the con’s control, this is the logical first step during cold weather paving. During production, asphalt mixture should be produced at the higher end of the appropriate range for the project’s asphalt binder.
